The authenticity and naturalism of Spencer Tracy's acting made him revered by his peers and beloved by the moviegoing public; he was the first actor to win back-to-back Best Actor statuettes from the Academy, for 1937's Captains Courageous (an adaptation of a Rudyard Kipling seafaring yarn) and 1938's Boys Town (in which he plays Father Flanagan, who insists "There is no bad boy."). This 1941 version of Robert Louis Stevenson's Dr. Jekyll and Mr. Hyde includes a dreamscape in which horses whipped by Hyde transform into the women in his life (Ingrid Bergman and Lana Turner). And in Bad Day at Black Rock (1954), Tracy plays a mysterious, one-armed veteran who comes to Black Rock and is met with threats and violence. Director John Sturges builds tension as Macreedy's mission and the town's grim secret are revealed.
